Your noise may come from something else.
It looks like you, and a couple of other folks that commented earlier, were right. It wasn't the axles at all. It was the sway bar.

Total noob move. Should have listened to you.

Luckily circlips aren't that expensive so I only wasted a bit of time. I replaced the circlip on one side and immediately realized that this didn't solve the problem. New circlips reduced the play but didn't eliminate it. After that, I started rattling stuff and found that the sway bar screws were loose.

Thanks all.
